As for the image, I'm not sure how to attach it to this reply. It's about 50 mg, 865x865. When I do a straight conversion from .eps to .jpg, the DPI shows 300dpi, which is fine. I'm just not sure how to change it to 72dpi when converting to .jpg.

Let me know if you need anything else. or how I could attaché my image.

ImageMagick does not update the density in the profiles. When you view it in Windows explorer it can still be using the value in the profiles. Can you try adding testImage.Strip() before you do testImage.Write?

Can you post your image on DropBox or a public image sharing service? Feel free to contact me through CodePlex if you don't want to share it publicly. I would like to investigate if I can update the profile in the image.

I just modified ImageMagick to update the 8BIM profile when an image is written. The next release of Magick.NET will include this fix. This means you no longer need to strip the 8BIM profile. I will also change the Density property to set the ResolutionUnits
to PixelsPerInch if ResolutionUnits is undefined.

I do have one final question. All of my image conversions are working very well except for one. It's fairly large, about 700mb. I do not get an error. My code acts as if the file converts, but the final file is only like 200kb. So, clearly it did not convert
properly. Should I have any concerns about converting an image that size? It's possible that it could be my own machine limitations, but wanted to double check with you first. If you are able to convert this file, then I'll figure out a way. A code snippet
would be nice, but not a big deal.

It seems the XMP profile in your file is very large. Under windows this generates a JPEG file that cannot be opened with the default image viewer of Windows. I will have to investigate if we can fix this problem. You could use image.RemoveProfile("XMP")
to resolve this problem.
